CHARLES FLEMING, OF YPSILANTI, MICHIGAN.

CAR-COUPLING.

SPECIFICATION forming partof Letters Patent No. 267,175, dated November '7, 1882.

Application filed April 6, 1882. (No model.) 4

To all whom it may concern:

Be it known that 1, CHARLES FLEMING, of Ypsilanti, in the county of Washtenaw and State of Michigan, have invented a new and useful Improvement in Oar-Couplings, of which the following is a specification.

, pin lowered.

Figure 1 is a vertical section with the pin raised. Fig. 2 is a vertical section with the Fig. 3 is an elevation of the pin and its supporting-rod. The rest of the figures are the same views as Figs. 1, 2, and 3, showing modifications of the construction of my invention.

My invention consists in a supporting-rod and coupling-pin so arranged that when the couplingpin is raised the supporting-rod will rest on the lower surface of the mouth of a draw-bar and hold the coupling-pin in a raised position.

In the drawings, D represents the end of a draw-bar, which may be of the usual form of east-iron or wrought-iron draw-bar.

Arepresents an ordinary cou pling-pin, which plays in holes K in the usual manner.

Brepresents a supporting-rod, pivoted to pin A by bolt 0, which may be secured by nuts L L, or in any convenient manner. BoltG passes through a slot out in supporting-rod B, sothat said rod-B may have a little play on said bolt. In Figs. 1 to 6 the supporting-rod B is made longer than pin A, so that when the lower end of the supporting-rod B rests on the lower surface of the mouth of the draw-bar the lower end of pin A will be clear of the mouth. Rod B in said figures is also shown as curved, so that when pin A is raised the lower end of said rod will tend to fall toward hole K, in which pin A plays. In Figs. 7 and 8 the supportingrod is attached to a shoulder or offset on the pin, and is not as long as in the other figures; but the principle is the same.

G S represent slots out through the top and bottom of the draw-bar, back of holes K, and in these slots the supporting-rod B plays.

f is a hole cut in the top of the supportingrod B, in which a rope or chain may be fastened, to allow the rod and pin to be raisedby a man standing above the draw-bar.

E is a stop fastened to the lower end of rod B, and is made too large to pass through slot G, thereby preventing removal of the rod and pin from the draw-bar. When the pin is lowered through the link R a shoulder, T, which may be on the rod B, as in Figs. 1 and 2, or on the pin, Figs. 4, 5, 7, 8, rests on the upper surface of the link R and holds the same horizontal.

The operation of my invention is so obvious that little explanation is necessary. If, when the pin is raised, as shown in Fig.1, a link R is thrust into the draw-bar, the end of the link will strike the lower end of rod B and push it backward until it falls through slot S, thus allowing pin A to fall through the link. Shoulder T now holds the linkin position to enter the draw-bar of another car. When rod B and pin A are raised the bottom of supporting-rod B will fall toward the end of the draw-bar, andwill rest upon link It until said link is withdrawn, when said rod will again assume the position shown in Fig. 1, and the coupling will be ready to act.

In the modification shown in Figs. 7 and 8 the supporting-rod B, when tripped by link R, falls back into the cavity F of the draw-bar, in stead of downward through a slot.

What I claim as my invention, and desire to secure by Letters Patent, is'- The combination of the draw-bar, the couplingpin, and the pin-supportingrod pivoted to theJatter, and arranged, substantially as shown and described, to swing and rest at its lower end on the interior lower surface of the mouth of the draw-bar when the coupling-pin is elevated, as and for the purpose set forth.
